Temp Low Point Calibration(Not proceed unless necessary, otherwise low accuracy)
Connect a standard 1000Ohm resistance externally with the circuit board then press for 3s and
release until value 1000.00 flashes; after this press
for 3s again until value 1000 Ohm stops
flashing then release. Temp Low point calibration is finished. Press
to enter next setting
interface.
Temp. Low Trim
1000.00 ohm
Temp High Point Calibration(Not proceed unless necessary, otherwise low accuracy)
Connect a standard 2500Ohm resistance externally with the circuit board then press for 3s and
release until value 2500.00 flashes; after this press
for 3s again until value 2500 Ohm stops
flashing then release. Temp High point calibration is finished. Press to enter next setting
interface.
Temp. High Trim
2500.00 ohm
Pressure Low Point Calibration(Not proceed unless necessary, otherwise low accuracy)
Connect a pressure sensor externally and input 0kpa then press for 3s and release until value
0.00000 is flashing; after this press
for 3s again and release until value 0.00000 stops flashing.
Pressure Low point calibration is finished. Press
to enter next setting interface.
Pre. Low Trim
0.000 kpa
Pressure High Point Calibration(Not proceed unless necessary, otherwise poor accuracy)
Connect a pressure sensor externally and input pressure, such as 1000kpa, and press
for 3s
and release until value 1000.00 is flashing; after this press
for 3s again and release until value
1000.00 stops flashing. Pressure High point calibration is finished. Press
to enter next setting
interface.
